Rental assistance is a major part of the welfare package offered to lo
w-income households. Unlike entitlement programs such as Aid to Famili
es with Dependent Children (AFDC). households must wait to receive hou
sing benefits. Researchers have overlooked the potential effect that v
ariance in the length of public housing waiting lists may have on intr
a-urban mobility rates. While households are typically eligible for th
e same housing benefit within a metropolitan area, the difference in t
he discounted stream of housing benefits thai a household can expect t
o receive may be substantial. Evidence in this paper suggests that int
ra-urban mobility is reduced by a small amount in metropolitan areas w
hich have higher median waiting times and which have less variation ac
ross waiting lists. (C) 1997 Academic Press.
